Alumina
High melting poi, thermal strength, high hardness and good thermal stability, adding alumina to
he friction material can effectively improve the normal temperature, high temperature friction
coefficie, which o reduce the heat caused by the recession due to friction plate cracking has
certain effec. It is not suit to add superfluous alumina i amou of he specific formula ,
general corol in 5% days, more than 325 mesh to avoid o increase abrasio and damage of duality.
